So on that note, what's the difference between that and regenerating their userbase when the word gets out that BD War Plots are happening at Neopets again. It will create an influx of members, many of whom will pay NeoCash for Battle Items in order to get them into the game faster... not to mention the extra cash they'd get with people playing games and viewing their ads.
The difference is the starting point for a new player is vastly different from an established BDer so you face an additional hurdle from people thinking it's just going to be the same players winning again compared to something like AC where everyone starts on Square one.
